A few days ago, there was a rumour At Well-Rounded Entertainment that Baldur's Gate III was being worked on and that it would use a 3D engine. Feargus Urquhart, the President of Black Isle Studios, provided the following statement:
There is no one working on Baldur's Gate 3. Between BioWare and Black Isle, we are just working on finishing up the products that we are currently developing.
Like I said, there probably will be a BGIII
. This was found in Planet Baldur's gate forums.
